HOW DO CHILDREN LEARN TO READ

♦ Substantial oral language interactions from birthonward.

♦ Extensive literacy interactions from birth onward.

♦ Using verbal interaction, language play, and oral reading to highlight the structure of the language.

♦ ALL NECESSARY BUT NOT SUFFICIENT


♦ They have developed an understanding that words that are spoken can be segmented into constituent abstract sounds (PHONEMES).

♦ PHONEMIC AWARENESS

4


♦ The development of phonemic awareness

(NECESSARY BUT NOT SUFFICIENT)

♦ Why can this be difficult for some children?

– Spoken language is seamless

– Co-articulation

– Speaking and listening do not require explicit knowledge of speech segments


♦ They have learned that print represents the sounds of speech. - The alphabetic principle

(NECESSARY BUT NOT SUFFICIENT)

♦ They have learned to connect letters and letter patterns to the sounds of speech.- Decoding and word recognition skills (NESESSARY BUT NOT SUFFICIENT)

5


♦ They have learned how to apply decoding and word recognition skills accurately and rapidly when reading words and text.

♦ They have learned how to use context to confirm accurate decoding and pronunciation of unknown words.

♦ THESE ARE NECESSARY BUT NOT SUFFICIENT FOR LEARNING TO READ


♦ Have learned strategies to maximize their reading comprehension.

– Can apply decoding and word recognition skills accurately and fluently.

– Have developed adequate background knowledge and vocabulary to ensure connections between what is known.

– Can actively employ language form and function (e.g. semantics, syntax, voice) to enhance comprehension.

– Can actively monitor their comprehension

6


♦ Good Comprehenders...

• Relate new information to existing knowledge

• Have well developed vocabularies

• Can summarize, predict, and clarify

• Use questioning strategies to guide

• Comprehension

NICHD EARLY INTERVENTION STUDIES

♦Scientific and Educational Goal

♦To determine for which children which instructional approaches and combinations of approaches are most beneficial at particular stages of reading development

- Children participating: 3,600 - Teachers participating: 1,012 - Schools Participating: 266 - Classrooms: 985 - States (including DC): 8

7

NICHD INTERVENTION STUDIES

♦ Methodological characteristics

- Theoretically based - Hypothesis driven - Samples defined to permit independent

replication - Instruction defined to permit independent replication

NICHD INTERVENTION STUDIES

♦ Methodological Characteristics

- All studies involve longitudinal designs to determine the effects of different interventions on language and reading growth over time.

- Studies designed to assess:- Different instructional components- Units of analysis- Degree of explicitness- Program Completeness

8

Special Education Does Not Close the Gap

♦Group sizes too large for pull out programs ♦Inclusion prevents effective practices for children

with LD ♦Models of service delivery demonstrably

ineffective for children with LD in reading ♦Occurs Too Late!!

Special Education Does Not Close the Gap

♦Teachers not adequately prepared ♦Identification based on failure ♦System oriented to procedural compliance, not

services and outcomes ♦Wait to Fail model that sometimes

stabilizes but rarely remediates!!

Francis et al. (1996)

10

Early Intervention is Possible

♦ Risk characteristics present in Kindergarten and G1 ♦ Letter sound knowledge, phonological awareness,

oral language development ♦ Assess all children and INTERVENE- first in the

classroom and then through supplemental instruction

Importance of Early Assessment and Intervention for Reading Problems

♦ Reading problems ♦ 74% of children identified in Grade 3 and identified as disabled in beyond require Grade 3 remained considerable disabled in 9th grade intervention. Children do (Francis et al., 1996) NOT simply outgrow reading problems.

11

Importance of Early Assessment and Intervention for Reading Problems

♦ Presence of risk characteristics are apparent in K and G1.

♦ 88% of students who were poor readers in G4; 87% of students who were good readers in G1 were also good readers in G4 (Juel, 1988).

♦ Stability in reading status from G1 to G5, this reading status was predictable based on K performance (Torgesen, 1997).

Early Intervention is Clearly Effective

♦ Torgesen (1997) identified children in K based on poor phonological awareness. By G2, 1:1 tutoring brought 75% to grade level reading. ♦ Vellutino et al. (1996) identified middle SES children

with very low word recognition skills at the beginning of G1. After 1 semester of 1:1 tutoring, 70% were on grade level.

13

Early Intervention is Clearly Effective

♦ Foorman et al. (1998): Classroom level reading intervention that provided explicit instruction in phonological awareness and the alphabetic principle as part of a balanced approach to reading brought G1-G2 students receiving Title 1 services to national averages relative to less explicit, inductive approaches.

A Widely Proposed Model If progress is inadequate, move to next level.

Level 1: Primary Intervention Enhanced general education classroom instruction.

Level 2: Secondary Intervention Child receives more intense intervention in general education, presumably in small groups.

Level 3: Tertiary Child placed in special education. Intervention increases in intensity and duration.

The Interventions ¾ Enhanced Classroom Instruction ¾ All children identified as at-risk for principal, teachers,

and parents ¾ Progress monitored with feedback to principal,

teachers, and parents ¾ Professional development of classroom teachers in

strategies for accommodating academic diversity and linking assessment to instructional planning for struggling readers

The Core Sample

Children – sampled across 2 years (2001- 2002) • 300 At-Risk Readers - assigned randomly to intervention. • 100 Low Risk Readers Teachers • 6 Intervention (3 Proactive & 3 Responsive) • 30 General Education 1st-grade Teachers Schools • 6 non-Title 1 elementary schools in a large urban school

district

16

Comparison of Two InterventionsComparison of Two Interventions

• Proactive and Responsive • 40 minutes, 5 days per week, all

school year (30 weeks) • 1:3 teacher-student ratio • Taught by certified teachers • Teachers are school employees,

but trained and supervised byresearchers

• Provided in addition to enhanced classroom instruction

Proactive InterventionProactive Intervention

• Explicit instruction in synthetic phonics, with emphasis on fluency.

• Integrates decoding, fluency, and comprehension strategies.

• 100% decodable text • Carefully constructed scope and

sequence designed to prevent possible confusions.

• Every activity taught to 100% mastery everyday.

17

Responsive InterventionResponsive Intervention

� Explicit instruction in synthetic phonics and in analogy phonics

� Teaches decoding, using the alphabetic principle, fluency, and comprehension strategies in the context of reading and writing

� No pre-determined scope and sequence

� Teachers respond to student needs as they are observed.

� Leveled text not phonetically decodable

18

A Comparison Between Responsive Reading and Reading Recovery

Responsive Reading Reading Recovery ♦ 1:3 teacher-student ratio (18

students per day) ♦ Daily 40-minute lessons ♦ School year (30 weeks) ♦ Letter and word work 10-12

minutes per day ♦ One word identification

strategy ♦ Children taught to sound out

words

♦ 1:1 teacher-student ratio (4students per half day)

♦ Daily 30-minute lessons ♦ 20 weeks ♦ Letter and word work 2-3

minutes per day (optional) ♦ Many word identification

strategies ♦ Children taught to use context

and pictures to help identifywords

Conclusions

♦ Development of reading skills dependent on establishment of LH neural network ♦ Network can be established through instruction, but is

interplay of brain and experience ♦ “We are all born dyslexic- the difference among us is

that of us are easy to cure and others more difficult” A.M. Liberman, 1996

26

Conclusions

♦ Primary and secondary level interventions appear effective in teaching at- risk children to read ♦ Affect a broad range of reading domains- word

recognition, fluency, comprehension ♦ Pullout approaches comparably effective- both

comprehensive, well- integrated with explicit phonics component: consistent with recent consensus reports

Early Intervention Reduces the At- Risk Population

♦ Primary alone: 5- 7% ♦ Secondary alone: 2- 6% ♦ Primary and Secondary: .01% to < 2%

27

Conclusions

♦ Three tier model has great promise for preventing most common cause of identification for special education ♦ Promotes joint responsibility of general education and

special education for all children ♦ No child should be placed in special education without

documentation of failure to respond adequately to scientifically- based instruction

Conclusions

♦Scaling up this model will require a significant investment in research ♦Many variables interact to produce outcomes:

child, classroom (teacher), school, community: For whom and how long??? ♦Adequate measurement and good tools are

essential, along with strong designs and large samples

28

Newer Federal Initiatives have Great Promise

♦Reading Excellence Act ♦No Child Left Behind ♦Reading First ♦Early Reading First
